Align Text Vertically in React Native

Question

I want to make my text like this in the picture. But my text is not centring vertically. How to achieve it?

What I have done so far is

<Fragment>
     <HeaderMain navigation={navigation}/>
     <View style={styles.subheader}>
       <Text style={styles.topText}>Заказы</Text>
     </View>
</Fragment>

Styles

container: {
    flex: 1,
    paddingHorizontal: 8,
    paddingVertical: 7,
    backgroundColor: '#E5E5E5',
},
subheader:{
    height: 55,
    backgroundColor: '#ffffff',
    flexDirection: 'column',
},
topText:{
    fontWeight: "bold",
    fontSize: 17,
    lineHeight:21,
    fontFamily: MONREGULAR,
    marginLeft: 16,
    justifyContent: 'center',
    alignItems: 'center',
},

Answer 1

You should not use justifyContent , alignItems in Text . You should use it in View . Also give lineHeight same values as your fontSize. Like this;

subheader:{
    height: 55,
    backgroundColor: '#ffffff',
    flexDirection: 'column',
    justifyContent: 'center',
},

topText:{
    fontWeight: "bold",
    fontSize: 17,
    lineHeight: 21,
    fontFamily: MONREGULAR,
    marginLeft: 16,
},

Answer 2

Try this subheader should be of display:flex and flex-direction:column topText should have justify-content:space-around

subheader:{
    height: 55,
    backgroundColor: '#ffffff',
    flexDirection: 'column',
    display: flex;
}

topText:{
    fontWeight: "bold",
    fontSize: 17,
    lineHeight:21,
    fontFamily: MONREGULAR,
    marginLeft: 16,
    justifyContent: 'space-around'
}

Answer 3

alignItems and justifyContent are used to adjust components within a view. If what you want is to center the content within a text you should use: textAlign, in your case I think you should use:

textAlign: "center"

Answer 4

subheader:{
  height: 55,
  backgroundColor: '#ffffff',
  flexDirection: 'column',
  justifyContent: 'center',
  alignItems: 'center',
},

topText:{
    fontWeight: "bold",
    fontSize: 17,
    lineHeight: 21,
    fontFamily: MONREGULAR,
    marginLeft: 16,
    justifyContent: 'center',
    alignItems: 'center',
},
